The vehicle can detect if certain wear parts need  
to be replaced or if malfunctions have occurred in  
vehicle systems. If the Telediagnostics service is  
activated, relevant data is automatically transmit-  
ted to the manufacturer. If fault conditions are  
detected by the vehicle system self-diagnosis, the  
system transmits recommendations for action to  
the Mercedes-Benz customer centre depending  
on the fault detected. The customer centre trans-  
mits the data to the service partner that you have

Active bonnet (pedestrian protection)  
Operation of the active bonnet (pedestrian pro-  
tection)  
In certain accident situations, the actuation of the  
active bonnet reduces the risk of injury to pedes-  
trians. The rear area of the bonnet is raised by  
approximately 75 mm.  
Aꢀer being triggered, the active bonnet remains in  
the raised position. Limited visibility due to the  
raised bonnet cannot be ruled out.
